Description

Technical Field

[0001] The present application relates to the technical field of heat exchange tube bundles, and in particular to a cooler heat exchange tube bundle. Background Art

[0002] A cooler is a device used to dissipate heat, and is mainly used in transformers, power electronic devices, engines, and other equipment. Since the converter generates a large amount of heat energy during operation, if the heat cannot be dissipated in time, the temperature of the equipment will be too high, thus affecting the normal operation and service life of the equipment.

[0003] However, the heat exchange tube bundle inside the cooler is generally a circular tube structure. The hot water is guided through the circular tube and the heat is dissipated by the circular tube. However, in the process of using the circular tube to guide the hot water, the heat dissipation effect of the heat flow in the middle of the circular tube is poor when the speed of the hot water is fast due to the long distance between the middle of the circular tube and the tube wall. Utility Model Content

[0004] One of the purposes of the present application is to improve the adequacy of heat exchange in a heat exchange tube bundle and to provide a cooler heat exchange tube bundle.

[0005] In order to achieve the above purpose, the technical solution adopted in the present application is: a cooler heat exchange tube bundle, including a guide tube bundle, a connecting tube bundle and a support plate; the cross-section of the guide tube bundle is a "+" structure, which is used to guide hot water; there are two groups of connecting tube bundles, and the two groups of connecting tube bundles are respectively installed at the two ends of the guide tube bundle, and the guide tube bundle is connected to the connecting tube bundle; there are two support plates, and the two support plates are respectively installed on the two groups of connecting tube bundles.

[0006] Preferably, the connecting tube bundle and the flow guiding tube bundle are rotationally connected, and a rotating mechanism is installed inside the connecting tube bundle.

[0007] Preferably, sleeves are fixedly installed at the middle of the pipe openings at both ends of the guide pipe bundle, and the sleeves are inserted into the connecting pipe bundle and connected to the connecting pipe bundle through a sealing bearing.

[0008] Preferably, the rotating mechanism includes a first support rod, a second support rod, a rotating rod and a spiral blade. The first support rod is fixedly mounted on the inner wall of the connecting tube bundle at one end away from the guide tube bundle, the second support rod is fixedly mounted on the inner wall of the sleeve, the rotating rod is rotatably mounted in the middle part between the first support rod and the second support rod, and the spiral blade is fixedly mounted outside the rotating rod.

[0009] Preferably, convex shells are evenly arranged on the outer wall of the flow guiding pipe bundle.

[0010] Compared with the prior art, the beneficial effects of this application are:

[0011] (1) The utility model is provided with a heat exchange tube bundle, a connecting tube bundle and a support plate, and the cross-section of the heat exchange tube bundle is set to a "+" structure. When the hot water passes through the heat exchange tube bundle, the contact area between the hot water and the tube wall of the heat exchange tube bundle is significantly increased due to the setting of the "+" structure. Compared with a round tube, there is no problem of insufficient heat dissipation caused by the hot water being far away from the tube wall.

[0012] (2) In the present invention, a rotating mechanism is provided. When the hot water passes through the connecting tube bundle and the heat exchange tube bundle, the flowing hot water drives the spiral blades to rotate. The rotating spiral blades drive the rotating rods to rotate, thereby driving the entire heat exchange tube bundle to rotate. The rotating heat exchange tube bundle can continuously change the flow trajectory of the external heat exchange medium, thereby significantly improving the uniformity and sufficiency of heat exchange.

[0018] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0021] One of the preferred embodiments of the present application is as follows: Figures 1 to 4 As shown, a cooler heat exchange tube bundle includes a guide tube bundle 3, a connecting tube bundle 1 and a support plate 2; the cross-section of the guide tube bundle 3 is a "+" structure, which is used to guide hot water; there are two groups of connecting tube bundles 1, and the two groups of connecting tube bundles 1 are respectively installed at both ends of the guide tube bundle 3, and the guide tube bundle 3 is connected to the connecting tube bundle 1; there are two support plates 2, and the two support plates 2 are respectively installed on the two groups of connecting tube bundles 1.

[0022] It can be understood that the entire device is installed inside the cooler shell, and a cavity is formed between the two support plates 2 and the cooler shell to isolate the air inlet end of the guide tube bundle 3 and the connecting tube bundle 1. By setting guide holes at the top and bottom of the cavity, the heat exchange medium flows through the guide holes, and the hot water flows from the inside of the guide tube bundle 3, thereby realizing heat exchange of the hot water. The cross-section of the guide tube bundle 3 is set to a "+" structure. In the process of the hot water passing through the guide tube bundle 3, due to the setting of the "+" structure, the contact area between the hot water and the tube wall of the guide tube bundle 3 is significantly increased. Compared with the round tube, there will be no problem of insufficient heat dissipation caused by the hot water being far away from the tube wall.

[0023] In this embodiment, the connecting tube bundle 1 and the flow guiding tube bundle 3 are rotationally connected, and a rotating mechanism is installed inside the connecting tube bundle 1. A sleeve 301 is fixedly installed in the middle of the two end pipe openings of the flow guiding tube bundle 3, and the sleeve 301 is inserted into the connecting tube bundle 1 and connected to the connecting tube bundle 1 through a sealed bearing. The rotating mechanism includes a first support rod 6, a second support rod 7, a rotating rod 4 and a spiral blade 5. The first support rod 6 is fixedly installed on the inner wall of the connecting tube bundle 1 away from the end of the flow guiding tube bundle 3, the second support rod 7 is fixedly installed on the inner wall of the sleeve 301, the rotating rod 4 is rotationally installed in the middle between the first support rod 6 and the second support rod 7, and the spiral blade 5 is fixedly installed outside the rotating rod 4.

[0024] It can be understood that when the hot water passes through the connecting tube bundle 1 and the guide tube bundle 3, the flowing hot water will drive the spiral blades 5 to rotate, and the rotating spiral blades 5 will drive the rotating rod 4 to rotate, thereby driving the entire guide tube bundle 3 to rotate. The rotating guide tube bundle 3 can continuously change the flow trajectory of the external heat exchange medium, thereby significantly improving the uniformity and sufficiency of heat exchange.

[0025] In this embodiment, Figure 4As shown, the outer wall of the flow guide tube bundle 3 is evenly provided with convex shells 302. The convex shells 302 can further increase the heat exchange area between the hot flowing water and the external heat exchange medium, thereby further improving the adequacy of heat exchange.
